Sensor Technology

 

One key sensor, the conductivity sensor, offers insights into oxygen levels within the dam. By identifying signs of eutrophication early on, researchers can intervene and mitigate the process. The IoT integration ensures seamless communication, allowing for swift responses to maintain wetlands in the dam's ecological balance.

What is a sensor?

 

A sensor is like a tiny electronic tool that can detect or measure things in the world around us. It can sense changes in light, temperature, pressure, or other conditions and send that information to a computer or another device so we can understand what's happening in our environment.

Oxygen Concentration Monitoring

About Oxygen:

 

The essential characteristics of oxygen - a chemical element denoted by the symbol O with an atomic number of 8. Oxygen is a vital gas crucial to the existence of living organisms. It's colorless, odorless, and tasteless, yet indispensable for the respiration of animals and photosynthesis in plants.

Understanding Concentration:

The concept of concentration in chemistry, particularly concerning oxygen,refers to the fraction of oxygen dissolved in or carried by a fluid.

 

Why Measure Oxygen Concentration in Water?

 

Monitoring oxygen levels in water is crucial for life. The concentration of oxygen in water correlates with the blending of saltwater from the sea and freshwater from wetlands. Decreases in oxygen levels can lead to detrimental consequences such as the death of aquatic life and plants.

Oxygen concentration over time

Here we show again a line chart. This time in the horizontal axis (x-axis) we represent the concentration of oxygen in the water. And in the vertical axis (y-axis) the same pariod of time represented in the above line chart.

What about Oxygen concentration?

  • About Oxygen >>
  • What it means concentration? In chemistry, the fraction of an element (in our case, Oxygen) dissolved in or carried by a fluid. More in /a> wikipedia >>
  • Why we are measuring the concentration of oxygen in the weter? The concentratiuon of oxygen in water is proportional to the amount of water from the sea (salted) mixed with the water from the wetlands (not salted).

Why Water Temperature Matters:

 

Water temperature significantly impacts biological activity, growth, and overall ecological health. Its effects on water chemistry, its influence on water quantity measurements, and its role in shaping aquatic habitats.

Explore the Range of Values:

 

The violin plots is a statistical visualization tool for comparing probability distributions. Much like box plots, violin plots offer insights into the spread of data, but with the added dimension of kernel density plots on each side.

 

Understanding Violin Plots:

 

The violin plot above represents the distribution of a variable across different categories. It shows temperature and provides a comprehensive view of both the diversity of values and their probability distribution.

 

 

Temperature monitoring can show an intricate interplay between water temperature and aquatic ecosystems. It provides a deeper understanding of environmental dynamics and the implications for ecosystem management and conservation efforts.

 

 

Monitoring Conductivity
